HEATING ATTACHMENT FOR LAMP-CHIMNEYS.

SPECIFICATION forming part of Letters Patent No. 460,693, dated October6, 1891.

Application filed December 16, 1890. Serial No. 374,928. (No model.)

To all whom it may concern:

Be it known that I, GEORGE L. THOMPSON, of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Heating Attachments for Lamp-Chimneys; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to improvements in the construction of heatingattachments for lamp-chimneys and it consists in the matters hereinafterdescribed, and more particularly pointed out in the appended claims.

In the accompanying drawings, illustrating my invention, Figure 1 is aview, partly in section, of the upper portion of a lamp-chimney, showingmy improved heating attachment arrangedfor heating a curling-ironapplied thereto. Fig.2 is a perspective view of one portion of myimproved heating attachment. Fig. 3 is a perspective View of anotherportion of the attachment. Fig. at is a central vertical section of myimproved heating attachment as adapted for heated liquids. Fig. 5illustrates a modified form of my improvement. Fig. 6 is a viewillustrating another modification of my improved heating attachment.

As shown in Figs. 1, 2, 3 and 4, A indicates, as a whole, an annular orring-shaped hollow body forming the attachment, said annular body beingsuitably shaped upon its under side to conform to the shape of the topof a lamp-chimney and adapted to rest upon the same.

The annular body A consists of an annular upper part B and an annularlower part B,.

suitably joined around their outer margins, as indicated at b. Theannular upper part B is provided with a central opening B preferablyhaving a downwardly-turned inner edge 1), and is further provided with aplurality of marginal draft-apertures b 11 The lower annular part B ispreferably formed, as shown more particularly in Figs. 1 and 4, with anannular shoulder 19 below which the lower portion of the part B iscontracted, so

as to fit within the inside of the top otgthe lamp-chimney, the shoulderhaving a bearing thereon. for use upon straight lamp-chimneys of smalldiameter, such as are used upon Argand burners, as well as uponchimneyshaving.

outwardly-flaring tops, I turn the lower margin of the part B inwardlyand form in its lower side a groove 5*. As indicated by the dottedlines, Fig. 1, the groove 1) receives the top of the straight lamp-chimney, so as to support the attachment firmly in place.

C indicates, as a whole, a removable annular filling-piece, formed fromtopand bottom plates, or disks C and C provided, respectively, withcentral apertures c and 0', through which a curling-iron may be passed,as in Fig. 1. The two parts C and C are joined in an y suitable mannerat their outer peripheries, and an annular shoulder or rib c ispreferably provided around the outside of the filling-piece C, which rib0 when the fillingpiece is in position, bears upon the upper inn ermargin of the piece B around the central opening therein.

By the employment of the removable filling-piece C, as shown in Figs. 1,2, 3 and 4, the attachment is adapted for use in heating a curling-ironwhile the piece C is in position, and by removing said piece it may beused for heating vessels containing liquids, 850.

In the form of construction shown in Fig. 5 the annular body D consistsof alower part D, corresponding in shape with the part B in the formshown in Figs. 1, 2, 3, and 4, and an upper part E, corresponding withthe part C, before described, and consisting of top and bottom plates ordisks E E provided with opposite central apertures e 6, through which acurling-iron may be inserted in the same manner, as hereinbeforedescribed, in connection with the form of device shown in Figs. 1 to 4.The lower part D is provided with a large central opening (Z and withannular bearing-surfaces cl and d similar to the bearing-surfaces b and1), before described, and is further provided with draft apertures daround its outer wall. In this form of construction the part E is heldin engagement with the part D by means of an up- In order to adapt theattachment turned flange d" upon the outer periphery of said part D,within which the part E is. inserted. Said flange d is preferably madeto closely embrace the outer periphery of the part E, so as to hold thepart E securely in place upon the lower part D, while at the same timethe parts D and E are separable, so as to permit the lowerpart alonetobe used for heating liquids in the same manner, as before described.

In Fig. 6 is shown another form of attachment,in which an annular body Fis employed, said body consisting of a lower part F and an upper part Fsaid parts being connected together at their outer peripheries, asindicated at f. The lower part F is provided with bearing-surfaces forengagement with the lamp-chimney, as before described. Draftapertures ff are provided around the outside of the upper part F and a centralaperture f for the insertion of a curling-iron is provided in said upperpart.

In the forms of construction shown in Figs. 1, 2, 3, and a by theemployment of the diaphragm C below the top plate or disk 0 of thefilling-piece, the heat from the burner is prevented from comingdirectly against the upper part of the said filling-piece when thedevice is in use as a curling -iron heater. Similarly, in the form shownin Fig. 5, by the employment of the diaphragm E the heat is preventedfrom coming into direct contact with the top plate E of the attachment.By this construction, when the device is in use as a curling-ironheater, theheat ispermitted to come into direct contact with thedepending curling-iron below the diaphragm, but is deflected outwardlyand awayfrom the center by said diaphragm, and therefore does notmaterially heat thehandle of the curling-iron, the space between thediaphragm and the upper plate or disk forming a dead-air space andpreventing the radiation of heat from the top of the lamp-chimney to thehandle of the curling-iron. By this construction, therefore, thecurling-iron may be heated to any desired degree and the handle of thecurlingiron kept cool, so as not to be uncomfortable to the hand of theuser.

As illustrated in Fig. 4, when the removable center or filling piece 0is removed the heated air and other products of combustion are permittedto come into direct contact with the bottom of a cup or other vesselplaced upon the top of the attachment, while a perfect draft is providedby the apertures b around the outer periphery of the annular body. Inthis form also the currents of heated air escaping through the apertures71 72 pass upwardly, coming into contact with the vessel containing theliquid around the outside of the ring-shaped body.

In the form shown in Fig. 5 the attachment is designed chiefly for useas a curling-iron heater; but a cup or other vessel may be plaeed uponthe top of the attachment.- In this construction raised projections d (lare provided, upon which the cup rests, so as to elevate the cupsomewhat above the top. of the annular upper part E and to permit acirculation of the gases and heated air between the bottom of the cupand said annular upper part E. In this instance a portion of said gaseswill pass through the central apertures e and e in said upper part E anddiaphragm E while the remaining portion of said gases pass outwardlythrough the marginal openings (1 d and upwardly into contact with thecup or other vessel.

In the form of construction shown in Fig. 6 the device may be usedeither for heating a curling-iron or for heating a vessel containingliquid. In heating a curling-iron the heat comes into direct contactwith the depending metallic portion of the curler below the upper part1of the annular body F, and is deflected by said upper part F", so as topass outwardly through the marginal apertures f f and away from thehandle of the curling-iron. \Vhen used for heating a vessel containingliquids, the heated gases and air flow through the apertures f f andcome against the vessel containing the liquid.

A main advantage gained by the construction of a heating attachment ofany of the constructions herein described is that by the arrangement ofthe annular body with a central aperture for the insertion of acurlingiron and with marginal draft-openings the handle of thecurling-iron is protected from the currents of heated air and gases, andis kept cool while the metallic portion of the curling-iron below thecentral aperture is being heated.

I claim as my invention 1. The herein-described heating attachment forlamp-chimneys, comprising a hollow annular body provided with centralapertures through its upper and lower walls and with a plurality ofmarginal draft-openings, and a centrally-apertured diaphragm locatedwithin said annular body below said upper wall and also provided with acentral opening, substantially as described.
